SAFETY FILM REEL.

Application filed July 21,

To all whom it may concern Be it known that I, LEO J. Dory, a citizen ofthe United States, residing at Kansas City, in the county of Jackson andState of Missouri, have invented a certain new and useful Improvement inSafety Film Reels, of which the following is a specification.

My invention relates to improvements in safety film reels.

My invention provides a novel hoop which is adapted to be ailixedreleasably to a film reel so as to completely cover the outer side of afilm held on the reel and which will protect the film from catchingfire.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred embodimentof my invention,

Fig. 1 is an end view partly broken away of a reel provided with myimprovement.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a perspective view of a portionof the reel, showing thereleasable locking means.

Fig. 4: is a perspective view of another portion of the reel, showingthe manner in which the hoop members are hinged to ether.

ig. 5 is a perspective view of one of the collars.

Fig. 6 is a perspective view of the hub.

Similar reference characters designate similar parts in the difi'erentviews.

1 designates each of two heads of a drum which has a hub 2 having itsends abutting respectively against the inner sides of the heads andwhich has fitted in it two collars 3 each having a peripheral extension4: fitted in. the adjacent one of two recesses 5 provided one in eachend of the drum. The drum is provided with a longitudinal slot 6 adaptedto receive one end of a movin picture film, not shown.

ounted concentrically in the drum hub 2 is a central tubular axle 7 theends of which abut respectively against the inner sides of the heads 1.The latter are provided each with a central opening 8 which is of thesame size and in alinement with the hole in the axle 7 and which isadapted to receive the shaft, not shown, which supports the reel inoperative position.

Rivets or bolts 9 which have shouldered portions abutting against theinner sides of 1919. fierial Ho. 312,15d.

the collars 3 extend through the collars and the heads 1, being rivitedto the latter, and thereby holding the parts together.

For covering and-protecting the film car- 60 --ried by the drum, whenthe film is not in use, I provide a hoop which is expansible andcontractible so as to be slipped on and off the heads 1, and which iscomposed, preferably of two members 10 and 11 which 65 have one set ofends overlapping, as shown in Flg. 4, said set of ends being hingedtogether by a link 12, the ends of which are respectively pivoted to twocleats 13 respectively secured to the outer sides of the members 10 and11. By connecting the members 10 and 11 with the link 12, pivotedthereto at a substantial distance from the adjacent ends of saidmembers, such ends will be swung Widely apart in the open position ofthe hook, thereby enabling the reel to be inserted therein more readilythan would be the case if an ordinary pintle hinge connection wereprovided.

The other set of ends of the members 10 and 11 are adapted, when thehoop is in the closed position shown in Fig. 3, to overlap, laidoverlapping ends being releasably held in the closed position by meansof'a locking cam lever 14, which is ivoted to one end of a link 15, theother en of which is pivoted to a cleat 16 attached to the outer side ofthe member 11. lhe locking hook 14 is adapted for releasable engagementwith one end of a link 17, the other end of which is pivoted to a cleat18 attached to the outer side of the member 10.

Each member 10 and 11 is provided at opposite side edges with inwardlyextending flanges 19, adapted to respectively embrace 9 the outer sidesof the heads 1.

Each of the members 10 and 11 is preferably provided at its oppositeedges with two grooves 20 adapted to respectively receive the outeredges of the heads 1, whereby M9 the heads are held apart.

In the operation of my invention, after the film has been placed on thehub 2, the hoop members 10 and 11 are fitted on the edges of the heads1, so that the free ends of said members overlap, as shown in Figs. 1and 3, after which the locking lever 14's is hooked through the link 17and then turned to the locking position, shown in Figs. 1 and 3, therebydrawing together and holding the members 10 and 11 firmly on the drumand completely covering the outer lltl lie

side of the tilm. Each head l is im er-forate hetweenthe peripheriesthereof an the hub 2, so that no spark or flame can reach the filmthrough. the closed heads. flhe heads are preferably of relativel fireproof material, such as sheet meta, steel or brass. The members 10 and11 are also of fire protective material, such as sheet'steel. /Vhenfitted on the heads 1, the members 10 and 11 form therewith a tightfireproof covering for the film. The holes 8 in the heads are of thesame size as the opening 2 of the axle 7. The ends of the latterabutting against the heads prevents the entrance in to the hub 2, at theouter side of the axle 7 of any sparks or flames. By employing the twolinks 15 and 17, a cam lever 14 may be utilized for fastening togetherthe free ends. of the members 10 and 11. By

the use of a cam lover, the members 10 and 11 are drawn forcibly toether in the locking operation and are 1151a securely locked in theclosed position.

To use the film, it is but necessary to release the locking lever letfrom the link 17, after which the members 10 and 11 may be swung to theopen position and removed eat en may be made without departing from thspirit of my invention.

What I claim is:

A safety film reel cover comprising two members having means forembracing the edges of'the heads of a film reel and having one set ofends which overlap each other hinged together, the other set of endsbeing adapted to overlap each other in the closed position, said membersWhere they overlap having their inner surfaces flush with each other,and means'for releasably locking together the free ends of said members,substantially as set forth.

In testimony whereof I have signed my name to this specification.
